Influenced by similarly all-female punk and post-punk acts like The Neo Boys and Kleenex, Grass Widow also note Roy Wood's The Move and The Kinks as a major source of inspiration. This can all be heard on Past Time along with the three-part harmonies, complex arrangements and odd chord progressions. Grass Widow is also influenced by a legacy of women who have paved the way through their music and politics. Their collaborative songwriting process, the fact that they don't have a front person and that they all equally contribute to the work of the band speaks to this philosophy. In addition, they take the opportunity as an all female band to bring attention to the roles of spectacle and spectator in their scene and make a conscious effort to play shows where women are involved.
